FASTENING FOR JARS.

,SPECIFICATION forming part of Letters Patent No. 515,010, datedFebruary 20, 1894.

Application filed May 19, 1893. Serial No. 474,754. (No model.) i

To alliwho'm/ it may concer-n;

Be it known that I, ROBERT I. PATTERSON, acitizen of the United States,residing at Muncie, 1n the county of Delaware and State of Indiana, haveinvented certain new and useful Improvements in Fastenings for Jars andthe Like; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theand useful improvements in fastenings espe- `cially designed for use inconnection with jars, bottles, and similar receptacles, and has for itsobject to provide a fastening of simple and cheap construction which inpractice is susceptible of being quickly applied to close the mouth ofthe receptacle with a minimum of time and labor, and of being as quicklydisconnected to open said mouth; and which by reason of its constructionis durable, and not liable to get out of order.

My invention consists essentially in afastener formed of a single pieceof wire, and in the detailsof construction and operation, all of whichwill fully and clearly appear .from a reading of the followingdescription taken in connection with the accompanying drawings whichform a partof this specification, and in which- Figure `l represents inperspective view a jar with my improved fastener applied there- Fig. 2is a side elevation of the same. Fig. 3 isa rear elevation of the same.Fig. 4 is a top View showing the fastening partially removed. Fig. 5 isa perspective view of the fastening detached; and Fig. 6 is aperspective view of a modification.

Like letters of reference denote like parts v Ain the several gures ofthe drawings.

The reference letter a denotes a jar of ordinary construction to whichmy :invention is applicable, although, as will be understood, thefastening may be advantageously employed in connection with bottles andother receptacles. -The neck'of the jar is provided with an annulariangeb on which'andaround said neck is placed a rubber or other suitablegasket c, and d is the cover having a depending annular flange adaptedto t over said neck and to rest and be clamped on said gasket.

The fastening is represented by the letter e, and is constructed of asingle piece of Wire preferably square in its cross section and havingsufficient resilience to enablethe fastening when made and applied tohold itself against displacement and impart the necessary pressure onthe cover. This fastening consists of the loop portion f in the form of,but slightly larger than a semi-circle, which partially'surrounds theneck of the jar or bottle below the fiange, and is made of a diameter alittle less t-han the diameter of the said neck in order that the samemay be spru ng and held in place. At the ends of theloop portion thewire is bent rearwardly at g on said loop for a short distance, in orderto permit of a vertical resilience, and is again bent vertically to formarms h which extend upward a distance equivalent to the height of thecover above the loop and is here bent and terminate in lugs fwhichengage the top of the cover on opposite sides as shown. The loopportionf is offset or bent upward at j, at equal points from the endsthereof, and this offset portion in practice finds a lodgment under theflange a'nd against the neck ofthe bottle. The arms h are preferablylocated at diametrically opposite points with relation to the jar, andthe rearward bend g is preferably parallel with the loop portion. Byreason of these features I obtain a lever action of the fastener, itbeing evident that as theloop is forced down to lodge the offset underthe ange, the lugs t' are thereby strongly pressed downward on the coverand the jar is securely locked and sealed.

In operation, the lugs are placed upon the upper surt'ace ot' the cover,and by gentle IOO to compensate for any irregularities that may exist inthe thicknessof the gasket or cover, and consequently all liability ofbreakage is overcome.

In Fig. 6 I have shown a fastener embodying all the essential featuresof my invention but in which the wire at the ends ot' the loop are bentdownwardly and rearwardly at 7c and then upwardly to pointsdiametrically opposite to each other and to the center of the cover. Theoperation of this modified form of construction is however substantiallythe same as that of the construction of fastener heretofore described,the only difference being that the bends form almost a true circle orspiral spring, Whereas in the first case the spring is ot' the torsionaltype.

The fastener when constructed in accordance With the foregoing is verysimple in operation and being formed of a single piece of wire may becheaply produced. It may be quickly applied and disconnected, and is notliable to become broken or to be disarranged.

Having now described and ascertained the nature of my invention and inwhat manner the same is to be performed, what I claim, and desire tosecure by Letters Patent, is

1. A fastening for jars and the like formed of a single piece of Wire,and comprising a loop adapted to be sprung about the neck of the jar orother article, and having its ends formed with return bends, upwardlyextending arms and lugs for engaging the cover, and an offset in theloop operat-ingin the manner and for the purposes set forth.

2. A fastener for jars and the like made of a single piece of wire bentto form a loop adapted to be sprung about the neck of the jar or otherarticle, and having its ends bent rearwardly, and then upwardly to formarms having lugs for engaging the cover, and an oliset in said loop,substantially as and for the purposes set forth.

In testimony whereof I aiiix mysignaturein presence of two Witnesses.
